That's what I meant: retrofitting the parts, not a build sheet "package."
I came across several posts on M3Forum when I was trying to order an Imola/black Bicolor steering wheel for my E39. Members were able to pull part umbers off RealOEM for the Individual Equipment and order them at the dealer to retrofit.
